Abstract: PURPOSE:To confirm an abnormal state of an electric power source, by providing a light emitting diode in parallel with a collector resistance, between the collector of a transistor for detecting and amplifying error voltage, and earth, and displaying the operating state. CONSTITUTION:When input voltage V1 rises, the emitter voltage of a transistor 3 rises. A collector current of the transistor 3 decreases. A base current and a collector current of a transistor 2 decrease. As a result, a base current of a transistor 1 decreases, a voltage drop by the transistor 1 becomes large, and output voltage V2 is kept constant. When V1 rises continuously, collector voltage V3 of the transistor 2 rises. When V3 exceeds voltage VA for starting turn- on of a light emitting diode 5, the light emitting diode 5 is turned on. When VA  is designed to voltage by which V2 becomes unstable, an abnormal state of the  electric power source is confirmed easily.

Filed: 1988-02-23
Abstract: PURPOSE:To obtain blue luminescence with a wavelength of 4.6X10<-5>cm which can be used for giving a full-color required to achieve a natural color display. CONSTITUTION:In an EL-panel of double insulating-film structure, a luminescent layer 4 is formed from Ta2O5. Electron avalanche phenomenon, wherein a large current is caused by the application of intense electric field, can occur in a Ta2O5 film 4, as in ZnS, SrS, CaS etc., so that the Ta2O5 film 4 can be utilized as a luminescent layer in the EL-panel. In the Ta2O5 film, band gap is 4.5eV and because of the occurrence of oxygen defect, 2.7eV level is formed, so that when a voltage is applied to this Ta2O5 film, the electron is trapped in the 2.7eV trap-level for producing blue luminescence with a wavelength of about 4.6X10<-5>cm. The high brightness luminescent of full-color, which is one of the three primary colors, required for producing natural color can thus be achieved.
